  • Wings 41 are provided on the upper end of the mounting plate 40 in such a way as to extend laterally, and a sidewall 46 is provided on the mounting plate 40 to be fitted into the module insert cavity 22 .
  • the mounting plate 40 is placed in back of the airbag cover 20 and is fixedly fastened to the airbag cover 20 .
  • the wall 21 surrounding the module insert cavity 22 and the sidewall 46 are fastened to each other using rivets 45 .
  • a central hole 44 is formed in the central portion of the mounting plate 40 to be electrically connected to an airbag control unit.
  • each remote control switch unit 30 includes a main body 31 and a subsidiary body 32 which is separable from the main body 31 .
  • the main body 31 is placed on the airbag cover 20 and provided with a switch part 31 f which is exposed to the front of the airbag cover 20 through the associated switch insert hole 23 of the airbag cover 20 .
  • the switch part 31 f has a size which is slightly smaller than the switch insert hole 23 , and parts other than the switch part 31 f are larger than the switch insert hole 23 . Referring to FIG. 3 , the switch part 31 f of the main body 31 is moved downwards to be inserted into the switch insert hole 23 , so that the main body 31 is mounted to the switch insert hole 23 . The operation of additionally fastening the main body 31 to the airbag cover 20 is not required.
  • a guide portion 31 c is provided in the back of the main body 31 , so that the subsidiary body 32 slides along the guide portion 31 c to be seated at a predetermined position or removed from the position.
  • a bracket 31 d having an “L”-shaped cross-section is provided in the longitudinal direction of the guide portion 31 c .
  • Tubes 31 a and 31 b each having an internal threaded part are provided around the guide portion 31 c , namely, provided at a position opposite to the bracket 31 d and a position in the sliding direction of the subsidiary body 32 .
  • Reference numeral 34 denotes a connector which is electrically connected to the switch part 31 f
  • reference numeral 31 e denotes a connector mounting hole.
  • the subsidiary body 32 is supported by the associated wing 41 of the mounting plate 40 and removably secured to the main body 31 and the mounting plate 40 .
  • the subsidiary body 32 and each wing 41 of the mounting plate 40 are fastened to each other via bolts 43
  • the subsidiary body 32 and the main body 31 are fastened to each other via piece bolts 33 .
  • fastening holes 32 d are formed in the upper surface of the subsidiary body 32 to correspond to through holes 42 which are formed in each wing 41
  • two ear parts 32 a and 32 b protrude from the side surface of the subsidiary body 32 to be coupled to the tubes 31 a and 31 b using the piece bolts 33 .
  • a flange 32 c protrudes laterally from the subsidiary body 32 to be fitted into the bracket 31 d.
  • the bolts 43 fastening each wing 41 of the mounting plate 40 to the subsidiary body 32 must be removed (see FIG. 5A ).
  • the piece bolts 33 fastening the subsidiary body 32 to the main body 31 must be removed (see FIG. 5B ).
  • the subsidiary body 32 corresponds to a member which is supported between the main body 31 and the associated wing 41 . Thus, after the subsidiary body 32 has been removed, it is possible to remove the main body 31 .
  • the subsidiary body 32 slides laterally along the guide portion 31 c of the main body 31 , so that the subsidiary body 32 is removed from its fastening position.
  • a step 31 g is provided on the back of the main body 31 corresponding to the fastening position, especially, at the innermost position in the longitudinal direction of the guide portion 31 c , thus stopping the subsidiary body 32 at a given position.
  • the ear part 32 a of the subsidiary body 32 must be positioned at a predetermined height such that it is placed right above the tube 31 a.

In detail, the main body 31 is lifted so that the switch part 31 f is completely removed from the switch insert hole 23 . Thereafter, as the main body 31 moves laterally, the main body 31 is removed from the switch insert hole 23 .
  • the height or thickness of the subsidiary body 32 is determined in consideration of the above-mentioned space.
  • the remote control switch unit 30 may be assembled with the driver airbag assembly 10 in the reverse order of the process of separating the remote control switch unit 30 from the driver airbag assembly 10 . Further, the first assembling operation of the driver airbag assembly 10 is performed as follows. That is, in the state where the cushion module 50 is seated in the module insert cavity 22 and the remote control switch unit 30 whose main body 31 and subsidiary body 32 are fastened to each other is seated in the switch insert hole 23 , the back of the airbag cover 20 is covered by the mounting plate 40 , and each wing 41 and the subsidiary body 32 are fastened to each other using the bolts 43 . Thereafter, the airbag cover 20 and the mounting plate 40 are fastened to each other using the rivets.
  • the flange 32 c is coupled with the bracket 31 d to easily guide the subsidiary body 32 along the guide portion 31 c while the subsidiary body 32 is separated from the main body 31 or the subsidiary body 32 is assembled with the main body 31 . Further, the flange 32 c is coupled with the bracket 31 d so that the subsidiary body 32 is temporarily secured at the fastening position on the main body 31 , thus allowing the main body 31 and the subsidiary body 32 to be easily fastened to each other using the piece bolts 33 .
  • the present invention provides a driver airbag assembly, which permits the easy separation and replacement of a remote control switch mounted to an airbag cover, regardless of whether the airbag cover and a mounting plate are riveted to each other.
